1982 Honda CB650SC Nighthawk Swingarm Locking Hardware

The 1982 CB650SC swingarm choice here is a lock nut and lock washer set. Match it to the pivot being serviced and inspect the remaining components before ordering. A two-piece locking package should be selected for that repair, especially where a previous owner changed the swingarm.

1982 Honda CB650SC Nighthawk · Swingarm Locking Hardware Buying guide

Compare the two locking pieces with the fitted pivot

The set contains one nut for reference 90354-425-830 and one washer for 90600-425-830. Confirm both against the actual assembly instead of assuming every component around the pivot is renewed by the same package.

Parts to consider

Use the confirmed two-piece contents

The package supplies one lock nut and one lock washer. Choose it for those locking pieces after comparing the existing pivot. Identify any separate bolt or bearing needs from the actual assembly and service information rather than expanding the set’s contents by assumption.

Verify the installed swingarm arrangement

A substituted swingarm can alter the pivot hardware despite the frame remaining the same. Compare the fitted components and follow the correct fitting and final-check procedure. The listed references establish part identity but not every adjustment or tightening requirement.

Swingarm Locking Hardware questions

Will a new locknut and washer cure swingarm side play?

Do not assume the visible fasteners are the cause. The product guidance calls for inspecting the pivot bolt, bushings or bearings, seals and frame bores, then setting pivot clearance by the Honda procedure. The package supplies only the locking nut and washer, not those other pivot components.

Can the lock washer be replaced by a similar-looking flat washer?

The set specifies a lock washer for reference 90600-425-830, paired with nut 90354-425-830. Preserve the prescribed locking arrangement and washer orientation, then follow the Honda tightening procedure and check smooth movement without side play. Appearance alone does not establish a substitute.

Will the set fit a non-original swingarm?

Confirm the installed pivot requirements first. The original 1982 CB650SC application does not establish compatibility with every replacement or custom swingarm.
